dc.description | Greenhouse tests were conducted to evaluate the effect of iprodione (Rovral®), fosetyl-AI (Alliete®), triadimephon (Bayleton 50DF®), SoilGard® (Gliocladium virens), pentachloronitrobenzene (PCNB) (Terraclor®), copper hydroxide (Champion®), benomyl (Benlate 50WP®) and "Garlic Barrier" in the population of Rhizoctonia solani and Myrothecium roridum. The most promising fungicides were evaluated at different dosages (X/2, X and 2X) to determine seedling protection and toxicity. Pentachloronitrobenzene, benomyl and iprodione were the most effective in reducing the population of ft solant in the inoculated soil with 93, 75 and 70% of inhibition, respectively. A phytotoxicity effect was observed in coffee seedlings treated with the double dosage of PCNB. The effect of fungicides was minimal in the reduction of the propagules of M. roridum when compared to the control although benomyl and triadimephon protected the seedlings against this pathogen. | en-US |
dc.description | Se realizaron pruebas de invernadero en donde se evaluó el efecto de la dosis recomendada de iprodione (Rovral®), fosetyl-AI (Alliete®), tríadimefon (Bayleton 50DF®), SoilGard® (Gliocladium virens), pentacloronitrobenceno (PCNB) (Terraclor®), hidróxido de cobre (Champion®), benomyl (Benlate 50WP®) y "Garlic Barrier" en la población de Rhizoctonia solani y Myrothecium roridum. Los fungicidas que resultaron promisorios se evaluaron a dosis diferentes (X/2, X y 2X) para determinar su protección y toxicidad a las plantas. El pentacloronitrobenzeno, benomyl e iprodione fueron los más efectivos en disminuir la población de R. solani en el suelo inoculado, con un porcentaje de inhibición de 93, 75 y 70%, respectivamente. Se observó un efecto de fitotoxicidad en las plántulas de cafeto tratadas con la dosis doble de PCNB. La eficacia de los fungicidas fue mínima en la reducción de los propágulos de M. roridum en comparación con el testigo, aunque benomyl y triadimefon protegieron las plántulas contra este patógeno. | es-ES |
